## Feature #7: FinOps-as-Code (Terraform Provider)

**Status**: ✅ Complete
**Test Coverage**: 37/37 tests passing

### Implementation

Infrastructure as Code support for OpenFinOps, enabling management of budgets, policies, alerts, and dashboards through declarative configuration.

#### Core Components

**1. Provider System** (`src/openfinops/iac/provider.py`)
- OpenFinOpsProvider with plan/apply/destroy workflow
- Resource lifecycle management (PENDING, CREATING, ACTIVE, UPDATING, DELETING, DELETED, FAILED)
- Validation and change detection

**2. Resource Definitions** (`src/openfinops/iac/resources.py`)
- `BudgetResource`: Budget management with alerts and notifications
- `PolicyResource`: Cost and compliance policy enforcement
- `AlertResource`: Threshold-based alerting
- `DashboardResource`: Dashboard configuration
- Full CRUD operations for all resources

**3. Terraform Generator** (`src/openfinops/iac/terraform_generator.py`)
- Generate Terraform HCL from Python resource definitions
- Provider block generation
- Resource block generation with proper formatting
- Module support with variables and outputs

**4. API Client** (`src/openfinops/iac/client.py`)
- REST API client for OpenFinOps server
- Methods for budget, policy, alert, and dashboard management
- Error handling and response validation

### Usage Example

```python
from openfinops.iac import OpenFinOpsProvider, budget, policy

# Initialize provider
provider = OpenFinOpsProvider(
    endpoint="https://finops.company.com",
    api_key="your-api-key"
)

# Create budget resource
monthly_budget = budget(
    name="production-budget",
    provider=provider,
    amount=10000.0,
    period="monthly",
    scope={"environment": "production"}
)

# Create policy resource
cost_policy = policy(
    name="cost-limit-policy",
    provider=provider,
    policy_type="budget",
    rules={
        "max_monthly_spend": 10000,
        "notify_at_threshold": 80
    }
)

# Plan and apply
provider.validate()
plan = provider.plan()
provider.apply(auto_approve=True)
```

### Key Technical Achievements

- **Dataclass Inheritance Fix**: Resolved initialization issues by implementing explicit `__init__` methods instead of relying on `@dataclass` decorators
- **Terraform HCL Generation**: Automated generation of valid Terraform configuration from Python objects
- **Resource Lifecycle**: Complete state machine for resource management

---

## Feature #8: SaaS Management & License Optimization

- Optimization recommendations (reduce, reclaim, consolidate)

**3. Usage Tracker** (`src/openfinops/saas/usage_tracker.py`)
- Activity levels:
  - ACTIVE: Used within 7 days
  - OCCASIONAL: Used within 30 days
  - INACTIVE: Used within 90 days
  - NEVER_USED: Never used
- Login and session tracking

    LicenseManager,
    UsageTracker,
    ShadowITDetector,
    LicenseType
)
from datetime import datetime, timedelta

# Discover SaaS applications
discovery = SaaSDiscovery()
billing_data = [
    {"vendor": "Slack", "amount": 15000, "date": "2025-01"},
    {"vendor": "GitHub", "amount": 5000, "date": "2025-01"}
]
apps = discovery.discover_from_billing(billing_data)

# License management
license_mgr = LicenseManager()
license_mgr.add_license(
    app_id="slack",
    license_type=LicenseType.SUBSCRIPTION,
    total_seats=100,
    cost_per_seat=15.0
)
license_mgr.assign_license("slack-1", "user123")

# Track usage
tracker = UsageTracker()
tracker.record_login("user123", "slack")

# Get optimization recommendations
recs = license_mgr.get_optimization_recommendations()
for rec in recs:
    print(f"{rec['type']}: {rec['description']} - Save ${rec['savings']:.2f}/mo")

# Shadow IT detection
detector = ShadowITDetector()
detector.add_approved_vendor("Slack")
shadow_apps = detector.detect_from_expenses(expense_data)
```

### Key Metrics

- **Utilization Rate**: `assigned_seats / total_seats`
- **Wasted Spend**: Cost of unused or underutilized licenses
- **Cost per User**: Total cost divided by active users
- **Activity Level**: Based on last login timestamp

### Key Technical Achievements

    cpu=4,
    memory=8
)
print(f"Cheapest: {report['savings_analysis']['cheapest_provider']}")

    cpu_cores=4,
    memory_gb=16,
    storage_gb=5000,
    network_gb_month=2000,
    database_instances=3
)

estimates = comparator.compare_workload(workload)
for est in estimates:
    print(f"{est.provider.value}: ${est.monthly_cost:.2f}/mo")

# Optimize workload placement
optimizer = MultiCloudOptimizer(strategy=OptimizationStrategy.COST)
result = optimizer.optimize_workload_placement(workload)
print(f"Recommended: {result['recommended_provider']}")
print(f"Monthly Cost: ${result['estimated_monthly_cost']:.2f}")

# Get migration plan
from openfinops.multicloud import CloudResource, ResourceType

current_resources = [
    CloudResource(
        resource_id=f"i-{i}",
        name=f"server-{i}",
        resource_type=ResourceType.COMPUTE,
        provider=CloudProvider.AWS,
        region="us-east-1",
        cost_per_hour=0.096
    )
    for i in range(10)
]

plan = optimizer.get_migration_plan(
    current_resources=current_resources,
    target_provider=CloudProvider.GCP,
    target_region="us-central1"
)
print(f"Migration Duration: {plan['estimated_duration_days']} days")
print(f"Estimated Savings: ${plan['estimated_savings']:.2f}/mo")
```

### Instance Type Selection

The system automatically selects appropriate instance types based on workload requirements:

**AWS**:
- `t3.micro`, `t3.small` (1 core)
- `t3.medium`, `t3.large` (2 cores)
- `t3.xlarge` (4+ cores)

**Azure**:
- `Standard_B1s`, `Standard_B1ms` (1 core)
- `Standard_B2s`, `Standard_D2s_v3` (2 cores)
- `Standard_D4s_v3` (4+ cores)

**GCP**:

- `n1-standard-1`, `n1-standard-2` (2 cores)
- `n1-standard-4` (4+ cores)

### Cost Breakdown

For each workload estimate, costs are broken down by:
- **Compute**: Instance costs (hourly rate × 730 hours × instance count)
- **Storage**: Storage costs (GB × cost per GB)
- **Network**: Data transfer costs (GB × cost per GB)
- **Database**: Database instance costs

### Key Technical Achievements

- **Unified Abstraction**: Single interface across AWS, Azure, and GCP
- **Intelligent Instance Selection**: Automatic selection based on CPU/memory requirements

## Known Limitations and Future Work

### FinOps-as-Code
- Terraform provider not yet published to Terraform Registry
- Limited to budgets, policies, alerts, and dashboards (no infrastructure resources)
- No state file encryption

### SaaS Management
- Pricing data based on simplified models (use actual vendor APIs in production)
- Limited SSO provider integrations (expand to more providers)
- No automated license reclamation (requires manual approval)

### Multi-Cloud
- Simplified pricing models (use cloud provider pricing APIs in production)
- Limited to compute, storage, network, and database resources
- No support for specialized services (AI/ML, serverless, containers)
- Migration planning is high-level (requires detailed execution plans)
